  • Rotary drives of the type described above in their basic structure are widely known and are used primarily to actuate switching devices, in particular high-voltage switching devices. With such part-turn actuators, the gear spindle can be operated by hand. As a rule, however, a drive motor is provided, the output shaft of which acts on the gear spindle of the swivel drive.
  • a rotational movement of the output shaft of approximately 180 ° is often required by the associated switching device, namely when the off position and the on position are opposite one another, that is to say offset from one another by 180 °.
  • a rotational movement of the output shaft of more than 180 ° is required if it is to be ensured that only the swivel drive can actuate the switching device, that is to say, other forces acting on the switching device do not lead to actuation of the switching device.
  • the invention is therefore based on the object to design and develop the swivel drive from which the invention is based so that its output shaft can easily perform a rotational movement of 180 ° or more than 180 °.

  • the teaching of the invention is based initially on the knowledge that a swivel drive of the type in question allows only a rotational movement of the output shaft, which is smaller than 180 °.
  • the first step according to the invention to a swivel drive of the type in question, the output shaft of which can execute a rotational movement of more than 180 ° now consists in assembling the link guide of the rocker from two guide parts, each guide part of the link guide then being able to be designed in this way without further ado that the output shaft each performs a rotational movement of more than 90 °, for. B. from 100 °, from 110 ° or also from 120 °.
  • the two guide parts of the link guide together then allow a rotational movement of the output shaft of much more than 180 °, z. B. from 200 °, from 220 ° or also from 240 °.
  • the spindle nut has a deflecting element and the rocker arm has a deflecting element assigned to the deflecting element of the spindle nut and that the driving pin of the spindle nut after passing through the first guide part of the link guide of the rocker arm through the interaction of the deflecting element of the spindle nut with the deflecting element of the rocker arm is guided into the second part of the stage guide.
  • the deflection elements provided according to the invention thus result in the driver pin of the spindle nut not coming to a dead center after passing through the first guide part of the link guide of the rocker or not moving back in the first guide part of the link guide of the rocker as the translational movement of the spindle nut progresses.
  • the two guide parts of the link guide of the rocker can be mirror-symmetrical and / or the deflecting element of the spindle nut can have a heart-shaped deflecting contour.
  • Rotary actuators of the type from which the invention is based are often additionally provided with a position indicator mechanism having a switch body.
  • position reports of the assigned switching device are realized, e.g. B. Position indicator contacts operated.
  • position reports for the off position and for the on position are required.
  • the invention consequently also relates to a swivel drive for switching devices, with a gear spindle, a spindle nut running on the gear spindle, at least one rocker arm, an output shaft connected to the rocker arm in a rotationally fixed manner, and a position indicator mechanism having a switch body.
  • This swivel drive in which the invention explained above is preferably implemented, is characterized according to a further teaching of the invention in that the link guide of the rocker has a leading area and / or a trailing area in which the driving pin of the spindle nut run without pivoting the rocker can that the switch body of the position indicator mechanism has a link guide, that the link guide of the switch body of the position indicator mechanism has a swivel range assigned to the leading area and / or the trailing area of the link guide of the rocker, and that the driver pin of the spindle nut also engages in the link guide of the switch body of the position indicator mechanism.
  • the pivoting areas of the link guide of the switching body of the position-reporting mechanism are preferably connected by a neutral area in which the driver pin of the spindle nut can run without pivoting the switching body.
  • a first preferred embodiment of the swivel drive according to the invention with a position reporting mechanism is additionally characterized in that the switching body is designed as a pivotable switching plate. It is advisable to make the driver pin of the spindle nut flat at its end which engages in the link guide of the switching body of the position indicator mechanism. Furthermore, the embodiment with a switching body designed as a pivotable switching plate can be characterized in that the switching body has at least partially an external toothing, the external toothing meshes with a gearwheel and position signaling contacts can be actuated with the aid of a position signaling shaft connected in a rotationally fixed manner to the gearwheel.

  • guide surfaces 7 assigned to the driving pins 5 of the spindle nut 2 are indicated in FIGS. 1 and 2.
  • the link guide 6 of the rocker arm 3 consists of two guide parts 6 a and 6 b, the spindle nut 2 has a deflecting element 8 and the rocker arm 3 has a deflecting element 9 assigned to the deflecting element 8 of the spindle nut 2 and becomes the driving pin 5 of the spindle nut 2 after it has passed through of the first guide part 6 a of the link guide 6 of the rocker arm 3 by the interaction of the deflecting element 8 of the spindle nut 2 with the deflecting element 9 of the rocker arm 3 in the second guide part 6 b of the link guide 6.
